Method and apparatus for processing autonomous transmission of user equipment

Abstract

A method for processing autonomous transmission of a User Equipment (UE), and a corresponding apparatus are provided. In the method, the UE receives first information transmitted by a network device. The first information includes autonomous transmission information, or information indicating activation or configuration of the autonomous transmission. The UE determines whether the autonomous transmission is configured or activated based on the first information. If it is determined from the first information that the autonomous transmission is configured or activated, the autonomous transmission is performed based on the first information. With the method, the autonomous transmission can be controlled based on the first information transmitted by a network, such that the implementation complexity of the UE can be reduced when the autonomous transmission of the UE and a network scheduled retransmission coexist, and the process is simple and clear, thereby reducing complexity of the UE and standardization work.
